[0013] In some embodiments of this application, the hinge mechanism is adapted to generate a thrust on the damper, the damper being adapted to be inserted into the cavity in the direction of the thrust and to be stopped in the direction of the thrust.

[0014] In some embodiments of this application, the damping mechanism further includes a headgear connected to the damping rod of the damper to be adapted to contact the hinge mechanism, wherein the end face area of ​​the headgear is larger than the end face area of ​​the damping rod of the damper.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0041] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0043] This application proposes a hinge device 3000, combined with... Figures 1 to 5 As shown, in some embodiments, the hinge device 3000 includes a hinge mechanism 3100 and a damping mechanism 3200. The damping mechanism 3200 is used to generate resistance to the movement of the hinge mechanism 3100. The hinge mechanism 3100 and the damping mechanism 3200 are independent components.

[0044] The hinge mechanism 3100 and the damping mechanism 3200 are independent components, ensuring that they do not affect each other's functions. If the damping mechanism 3200 fails, it can be repaired and replaced separately, and vice versa. This means that if either the hinge mechanism 3100 or the damping mechanism 3200 fails, the entire hinge device 3000 does not need to be replaced, reducing maintenance costs. Furthermore, because the hinge mechanism 3100 and the damping mechanism 3200 are independent components, the hinge device 3000 can still function using the hinge mechanism 3100 even without the damping mechanism 3200. This allows the hinge device 3000 to switch freely between damped and non-damped modes, improving standardization and production efficiency.

[0045] The following description uses a household appliance as an example to illustrate the hinge device 3000. This appliance can be an oven, steam oven, microwave oven, etc. The appliance includes a body 1000 and a door 2000. The body 1000 has a receiving cavity for placing food or other objects. The door 2000 is used to close and open the receiving cavity. The door 2000 and the body 1000 are connected via the hinge device 3000 to enable the door 2000 to open and close. Specifically, a portion of the hinge device 3000 is connected to the body 1000, and another portion is connected to the door 2000.

[0046] The movement of the door 2000 is achieved through the movement of the hinge mechanism 3100. To avoid excessive impact between the door 2000 and the body 1000 when the door 2000 closes, a damping mechanism 3200 is provided. The damping mechanism 3200 works in conjunction with the hinge mechanism 3100 to resist the movement of the hinge mechanism 3100. That is, when the door 2000 switches from the open state to the closed state, the hinge mechanism 3100 exhibits corresponding movement. During the movement of the hinge mechanism 3100, it works in conjunction with the damping mechanism 3200. The damping mechanism 3200 resists the movement of the hinge mechanism 3100, reducing the energy of the hinge mechanism 3100's movement, thereby achieving a damping effect. This allows the door 2000 to close slowly, avoiding excessive impact on the body 1000 when the door 2000 closes. For details on the resistance generated by the damping mechanism 3200 to the movement of the hinge mechanism 3100, please refer to related technologies. The damping mechanism 3200 can be of various types, including spring damping mechanism, hydraulic damping mechanism, and pulse damping mechanism.

[0047] In this embodiment, the hinge mechanism 3100 and the damping mechanism 3200 are independent components. "Independent" means that the function of the hinge mechanism 3100 is not affected by the damping mechanism 3200, and vice versa. The hinge mechanism 3100 only engages with the damping mechanism 3200 when the hinge device 3000 is assembled. For example, the hinge mechanism 3100 and the damping mechanism 3200 can be manufactured independently. The hinge mechanism 3100 has its own hinge function, and the damping mechanism 3200 has its own damping effect. Therefore, if the damping mechanism 3200 of the hinge device 3000 is damaged, it can be repaired and replaced separately. Similarly, if the hinge mechanism 3100 of the hinge device 3000 is damaged, it can be repaired and replaced separately. This eliminates the need to replace the entire hinge device 3000, effectively reducing maintenance costs.

[0048] It is understandable that, for different household appliances, the hinge device 3000 can have a damping effect or not. A damping effect means the hinge device 3000 has a damping mechanism 3200, while a non-damping effect means the hinge device 3000 does not have a damping mechanism 3200. In this embodiment, since the hinge mechanism 3100 and the damping mechanism 3200 are independent components, the presence or absence of the damping mechanism 3200 does not affect the movement of the hinge mechanism 3100. That is, when the hinge device 3000 needs a damping effect, the damper 3220 is installed; when the hinge device 3000 does not need a damping effect, the damper 3220 is removed. Through this design, the same set of hinge devices 3000 can freely switch between having a damping effect and not having a damping effect according to actual needs, without the need for separate molds for hinge devices 3000 with and without damping effects. This effectively reduces the amount of material, improves standardization, and thus increases production efficiency.

[0049] Continue to combine Figures 1 to 5 As shown, in some embodiments, the hinge device 3000 further includes a mounting base 3300, a hinge mechanism 3100 connected to the mounting base 3300, and a damping mechanism 3200 connected to the mounting base 3300.

[0050] Specifically, the mounting base 3300 is a main structural component of the hinge device 3000, supporting other parts of the hinge device 3000 and providing a support foundation for its normal operation. The mounting base 3300 can be made of metal or other materials. The hinge mechanism 3100 and the damping mechanism 3200 need to be connected to the mounting base 3300, with the mounting base 3300 supporting both the hinge mechanism 3100 and the damping mechanism 3200. For example, the mounting base 3300 may have a U-shaped cross-section, shielding the damping mechanism 3200 and most of the structure of the hinge mechanism 3100 (such as shielding the hinge bracket 3130 and the second connecting arm 3120 of the hinge mechanism 3100). It is understood that when the hinge device 3000 does not have a damping effect, the damper 3220 does not need to be mounted on the mounting base 3300.

[0051] As mentioned above, a portion of the hinge device 3000 is connected to the body 1000, and another portion is connected to the door 2000. Given that the hinge device 3000 includes a mounting base 3300, the mounting base 3300 can be connected to the body 1000, and the door 2000 can be connected to the hinge mechanism 3100, thus assembling the hinge device 3000. Alternatively, the hinge mechanism 3100 can be connected to the body 1000, and the door 2000 can be connected to the mounting base 3300, also achieving the assembly of the hinge device 3000. Taking the former as an example, when assembling the hinge device 3000, simply connecting the mounting base 3300 to the body 1000 secures the hinge device 3000 to the body 1000, and then connecting the hinge mechanism 3100 to the door 2000 completes the assembly of the body 1000, the door 2000, and the hinge device 3000. It is understandable that even when the hinge device 3000 does not have a damping effect, that is, when the damping mechanism 3200 is eliminated, the hinge device 3000 is still connected to the body 1000 through the mounting base 3300.

[0052] In some embodiments, the hinge mechanism 3100 is designed to be detachably connected to the mounting base 3300. For example, the hinge mechanism 3100 achieves a detachable connection to the mounting base 3300 through at least one of snap-fit, screw-fit, pin-fit, and interference fit. As mentioned above, when the hinge mechanism 3100 is damaged and needs repair or replacement, the detachable connection between the hinge mechanism 3100 and the mounting base 3300 facilitates the disassembly and installation of the hinge mechanism 3100 without requiring excessive destructive operations, thus improving convenience. Similarly, the damping mechanism 3200 is also designed to be detachably connected to the mounting base 3300, and the detachable connection method can be at least one of snap-fit, screw-fit, pin-fit, and interference fit.

[0053] Combination Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments, the hinge mechanism 3100 and the damping mechanism 3200 are arranged along a first direction, for example, the first direction is the front-to-back direction, and the hinge mechanism 3100 is located in front of the damping mechanism 3200. This makes the installation and removal of the hinge mechanism 3100 and the damping mechanism 3200 independent of each other. The hinge mechanism 3100 can be installed first and then the damping mechanism 3200 can be installed later, or the damping mechanism 3200 can be installed first and then the hinge mechanism 3100 can be installed later. The same applies to disassembly.

[0054] Combination Figures 11 to 13As shown, in some embodiments, the damping mechanism 3200 is provided with a first connecting part 3211 and a second connecting part 3212. The first connecting part 3211 is used for pre-positioning connection with the mounting base 3300, while the second connecting part 3212 is used for fastening connection with the mounting base 3300. Through the provision of the first connecting part 3211 and the second connecting part 3212, the connection and fixation between the damping mechanism 3200 and the mounting base 3300 are realized.

[0055] Specifically, the mounting base 3300 has connection structures corresponding to the first connecting part 3211 and the second connecting part 3212. When assembling the damping mechanism 3200 onto the mounting base 3300, the first connecting part 3211 is first engaged with the corresponding connection structure of the mounting base 3300 to achieve a pre-positioning connection. This forms an initial positioning constraint on the damping mechanism 3200, improving the assembly accuracy of the damping mechanism 3200. Since the damping mechanism 3200 needs to cooperate with the hinge mechanism 3100 and provide resistance, the accurate installation of the damping mechanism 3200 has a significant impact on the damping effect. In this embodiment, the initial positioning constraint of the first connecting part 3211 effectively achieves the accurate positioning of the damping mechanism 3200, making it less prone to displacement during subsequent tightening. After the damping mechanism 3200 achieves a pre-positioning connection through the first connecting part 3211, it needs to be tightened by the second connecting part 3212 and the corresponding connection structure of the mounting base 3300, thus achieving stable assembly of the damping mechanism 3200.

[0056] For example, the first connecting part 3211 is a snap-fit, and the corresponding connecting structure on the mounting base 3300 is a snap-fit ​​hole 3310. The snap-fit ​​is snapped into the snap-fit ​​hole 3310 to achieve a pre-positioning connection of the damping mechanism 3200. The cooperation between the snap-fit ​​and the snap-fit ​​hole 3310 enables quick assembly of the damping mechanism 3200 and the mounting base 3300, which improves assembly efficiency. It is understood that the snap-fit ​​can be snapped into the snap-fit ​​hole 3310 or disengaged from it along the reverse path. Therefore, the second connecting part 3212 is needed to secure the snap-fit ​​to prevent separation from the snap-fit ​​hole 3310.

[0057] There are also various ways to secure the second connecting part 3212 to the mounting base 3300, for example, by continuing to combine Figures 11 to 13As shown, the second connecting part 3212 is a connecting hole, and the corresponding connecting structure on the mounting base 3300 is a fastening hole 3320. After the damping mechanism 3200 achieves a pre-positioned connection with the mounting base 3300 through the first connecting part 3211, the connecting hole and the fastening hole 3320 correspond. By passing a fastener through the connecting hole and the fastening hole 3320, the damping mechanism 3200 and the mounting base 3300 can be fastened together. The connecting hole and the fastening hole 3320 may be provided with internal threads, and the fastener may be provided with external threads. The fastener passes through the connecting hole and the fastening hole 3320 and achieves fastening through thread engagement.

[0058] Combination Figure 1 , Figure 2 as well as Figures 11 to 13 As shown, in some embodiments, where the first connecting part 3211 is a snap fastener and the mounting base 3300 is provided with a snap hole 3310, the engagement between the snap fastener and the snap hole 3310 is carried out in the following manner: the hinge mechanism 3100 generates a thrust on the damping mechanism 3200, and the snap fastener is engaged in the snap hole 3310 along the direction of the thrust.

[0059] Specifically, the movement of the door body 2000 will cause the hinge mechanism 3100 to move accordingly. During the movement of the hinge mechanism 3100, it will come into contact with the damping mechanism 3200, and the hinge mechanism 3100 will exert a thrust on the damping mechanism 3200, pushing the corresponding parts of the damping mechanism 3200 to move, thus being resisted by the damping mechanism 3200.

[0060] For example, the damping mechanism 3200 includes a damper 3220, and the damping rod 3222 of the damper 3220 is telescopically configurable. When the door 2000 is closed, the door 2000 drives the hinge mechanism 3100 to push the damping rod 3222 to move. During the movement of the damping rod 3222, it encounters resistance (the damper 3220's own function is realized), thereby generating resistance to the movement of the hinge mechanism 3100. In this case, except for the damping rod 3222, the other components of the damping mechanism 3200 should remain fixed, otherwise the damping effect will be greatly reduced.

[0061] To improve the fixing effect of the damping mechanism 3200, in this embodiment, taking the hinge mechanism 3100 pushing the damping mechanism 3200 backward as an example, the buckle bends backward and snaps into the buckle hole 3310, which is stopped by the edge of the buckle hole 3310. Since the hinge mechanism 3100 pushes the damping mechanism 3200 backward, the edge of the buckle hole 3310 blocks the buckle from the rear, thereby improving the stability of the damping mechanism 3200 and making it less likely to loosen.

[0062] Combination Figure 3 , Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, the damping mechanism 3200 includes a damper 3220 and a damping bracket 3210. The damper 3220 is connected to the damping bracket 3210, and the damping bracket 3210 is connected to the mounting base 3300, thus connecting the damping mechanism 3200 to the mounting base 3300. For example, the damping bracket 3210 is provided with the first connecting portion 3211 and the second connecting portion 3212 mentioned above.

[0063] Specifically, the damping mechanism 3200 provides resistance to the movement of the hinge mechanism 3100 through a damper 3220, which can be of various types, such as a spring damper, a hydraulic damper, or a pulse damper. When the door 2000 switches from the open state to the closed state, the hinge mechanism 3100 exhibits corresponding movement. During the movement of the hinge mechanism 3100, it cooperates with the damper 3220 to generate resistance to the movement of the hinge mechanism 3100, reducing the energy of the hinge mechanism 3100's movement and achieving a damping effect, causing the door 2000 to close slowly and preventing the door 2000 from causing excessive impact on the machine body 1000.

[0064] Generally, the damper 3220 is a mature component and is not convenient to directly assemble and fix onto the mounting base 3300. In this embodiment, the damper 3220 is installed using a damping bracket 3210 to assemble the damper 3220 onto the mounting base 3300. The damping bracket 3210 is a main structural component of the damping mechanism 3200, providing support for other components of the damping mechanism 3200 and providing a support foundation for the normal operation of the damping mechanism 3200. The damping bracket 3210 can be made of metal or other materials.

[0065] Combination Figure 12 As shown, in some embodiments, the damping bracket 3210 is provided with a cavity 3213, into which the damper 3220 is inserted and fixed. This facilitates the assembly of the damper 3220 and the damping bracket 3210 while ensuring a secure connection. For example, the cavity 3213 has a certain depth, which is adapted to the length of the damper 3220. One end of the cavity 3213 is open, and the damper 3220 is inserted into the cavity 3213 from the open end. Thus, in the direction surrounding the damper 3220, the damper 3220 is constrained by the cavity wall of the cavity 3213, achieving effective fixation of the damper 3220.

[0066] Optionally, combined Figure 1 , Figure 2 and Figure 12As shown, the damper 3220 is adapted to be inserted into the cavity 3213 in the direction of the thrust generated by the hinge mechanism 3100 on the damper 3220, and is stopped in the direction of the thrust.

[0067] For example, when the hinge mechanism 3100 is active, it pushes the damping rod 3222 of the damper 3220 backward. The hinge mechanism 3100 generates a backward thrust on the damping rod 3222 and drives the damping rod 3222 to move backward. In this embodiment, the cavity 3213 of the damping bracket 3210 is open to the front. The damper 3220 is inserted into the cavity 3213 from front to back and is stopped. Thus, when the hinge mechanism 3100 is active and pushes the damping rod 3222 to move backward, in addition to the damping rod 3222 moving backward, the other parts of the damper 3220 (body part 3221) are stopped by the damping bracket 3210 to prevent the damper 3220 from becoming loose. The damper 3220 is stopped in the direction of the thrust. This can be because the damper 3220 is stopped by the bottom of the cavity 3213, or because the damper 3220 is provided with a stop structure. During the process of the damper 3220 being inserted into the cavity 3213, the stop structure is stopped by the open end of the cavity 3213. Compared with the latter, the former structure is simpler.

[0068] Combination Figure 5 , Figure 7 , Figure 11 and Figure 12 As shown, in some embodiments, the damping mechanism 3200 further includes a head cover 3230, which is connected to the end of the damping rod 3222 and is used to contact the hinge mechanism 3100. Specifically, the damper 3220 includes a body portion 3221 and a damping rod 3222 telescopically disposed on the body portion 3221. When the damping rod 3222 moves relative to the body portion 3221, it can generate resistance in the damper 3220. The head cover 3230 is connected to the end of the damping rod 3222 that is away from the body portion 3221. For example, the head cover 3230 is provided with a socket, and the damping rod 3222 is inserted into the socket so that the head cover 3230 is connected and fixed to the damping rod 3222.

[0069] When the hinge mechanism 3100 is in motion, it contacts the head sleeve 3230, thereby pushing the damping rod 3222. In this embodiment, the end face area of ​​the head sleeve 3230 is designed to be larger than the end face area of ​​the damping rod 3222. That is, the contact area between the head sleeve 3230 and the hinge mechanism 3100 is larger than the contact area between the damping rod 3222 and the hinge mechanism 3100. This can increase the friction and enhance the contact conduction between the damping mechanism 3200 and the hinge mechanism 3100, making the contact between the damping mechanism 3200 and the hinge mechanism 3100 more stable.

[0070] Optionally, in some embodiments, the headgear 3230 is adapted for elastic deformation. For example, the headgear 3230 is made of an elastically deformable material such as rubber or silicone. The headgear 3230 deforms when subjected to force and returns to its shape when the force is removed. The deformation of the headgear 3230 also increases the contact area with the hinge mechanism 3100. By designing the headgear 3230 to be elastically deformable, the impact noise at the moment of contact between the hinge mechanism 3100 and the damping rod 3222 can be reduced, thus avoiding noise generation.

[0071] Combination Figures 7 to 10 As shown, in some embodiments, the hinge mechanism 3100 includes a hinge bracket 3130, a first connecting arm 3110 and a second connecting arm 3120. The first connecting arm 3110 is rotatably connected to the hinge bracket 3130, the hinge bracket 3130 is connected to the mounting base 3300, and the first connecting arm 3110 can be used to drive the second connecting arm 3120 to move.

[0072] Specifically, the hinge bracket 3130 is the main structural component of the hinge mechanism 3100, which supports other parts of the hinge mechanism 3100 and provides a support foundation for the normal operation of the hinge mechanism 3100. The hinge bracket 3130 can be made of metal or other materials.

[0073] The first connecting arm 3110 is rotatably connected to the hinge bracket 3130. The first connecting arm 3110 is rotatable relative to the hinge bracket 3130, and it needs to cooperate with the second connecting arm 3120 to drive the second connecting arm 3120 to move. Taking the door 2000 driving the first connecting arm 3110 to rotate as an example, when the door 2000 opens or closes, it drives the first connecting arm 3110 to rotate. The rotation of the first connecting arm 3110 drives the second connecting arm 3120 to move, so that the second connecting arm 3120 can cooperate with the damping mechanism 3200. When the door 2000 is closed, it drives the first connecting arm 3110 to rotate. The first connecting arm 3110 drives the second connecting arm 3120 to act on the damping mechanism 3200 (pushing the damping rod 3222), thus experiencing the resistance generated by the damping mechanism 3200.

[0074] It is understandable that the cooperation between the first connecting arm 3110 and the second connecting arm 3120 (the first connecting arm 3110 drives the second connecting arm 3120) can be found in related technologies. For example, the second connecting arm 3120 and the first connecting arm 3110 can be rotatably connected (either directly or indirectly). The second connecting arm 3120 is provided with a sliding protrusion 3122, and the hinge bracket 3130 can be provided with a sliding groove 3132. The sliding protrusion 3122 is inserted into the sliding groove 3132, and the sliding protrusion 3122 can slide in the sliding groove 3132. Taking the door body 2000 driving the first connecting arm 3110 as an example, when the door body 2000 drives the first connecting arm 3110 to rotate, the first connecting arm 3110 drives the second connecting arm 3120 to move. Since the second connecting arm 3120 is rotatably connected to the first connecting arm 3110 and slidably connected to the hinge bracket 3130, it can reciprocate following the rotation of the first connecting arm 3110, thereby achieving cooperation with the damping mechanism 3200.

[0075] Furthermore, combined Figure 9 and Figure 10 As shown, in some embodiments, the hinge mechanism 3100 further includes a spring 3140, which is sleeved on the second connecting arm 3120. The second connecting arm 3120 is provided with a second stop 3121, and the hinge bracket 3130 is provided with a first stop 3131. One end of the spring 3140 is connected to the first stop 3131, and the other end of the spring 3140 is connected to the second stop 3121. For example, the spring 3140 is disposed between the first stop 3131 and the second stop 3121, with both ends of the spring 3140 abutting against the first stop 3131 and the second stop 3121 respectively. The spring 3140 assists in the opening and closing of the door 2000.

[0076] As described above, a portion of the hinge device 3000 is connected to the body 1000, and a portion of the hinge device 3000 is connected to the door body 2000. For example, combining... Figures 4 to 6 As shown, the mounting base 3300 is connected to the body 1000 and the door 2000 is connected to the hinge mechanism 3100. This hinge device 3000 is considered a horizontal hinge device 3000. Alternatively, the hinge mechanism 3100 can be connected to the body 1000 and the door 2000 can be connected to the mounting base 3300. This hinge device 3000 is considered a vertical hinge device 3000.

[0077] Taking the mounting base 3300 connected to the body 1000 and the hinge mechanism 3100 connected to the door 2000 as an example, combined with Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the hinge mechanism 3100 is connected to the door body 2000 through the first connecting arm 3110, that is, the first connecting arm 3110 is connected to the door body 2000.

[0078] When the door 2000 is opened (rotating from top to bottom), the door 2000 drives the first connecting arm 3110 to rotate. During the rotation of the first connecting arm 3110, the second connecting arm 3120 moves (moves forward). The second connecting arm 3120 gradually moves away from the damping mechanism 3200 (moves forward), and the spring 3140 deforms (compresses) to prevent the door 2000 from rotating downward quickly.

[0079] When the door 2000 closes (rotates from bottom to top), the door 2000 drives the first connecting arm 3110 to rotate. During the rotation of the first connecting arm 3110, the second connecting arm 3120 moves (moves backward). The spring 3140 returns to its original position (extends). The spring 3140 provides some assistance to the user in controlling the closing of the door 2000. The second connecting arm 3120 gradually approaches (moves backward) the damping mechanism 3200 and pushes the damping mechanism 3200. The second connecting arm 3120 abuts against the head cover 3230 of the damping mechanism 3200 and drives the damping rod 3222 to move (move backward). This causes the damping mechanism 3200 to generate resistance against the second connecting arm 3120 (hinge mechanism 3100), thereby creating a damping effect on the door 2000, causing the door 2000 to close slowly and preventing the door 2000 from hitting the body 1000 and generating noise.

[0080] It is understandable that the rotation of the door 2000 is an action, that is, the body 1000 rotates relative to the door 2000. Therefore, when the mounting base 3300 is connected to the door 2000 and the hinge mechanism (first connecting arm 3110) is connected to the body 1000, it also has a similar technical effect, which will not be repeated here.

[0081] The second aspect of this application discloses a household appliance, combined with Figures 1 to 6 As shown, the household appliance includes the hinge device 3000 mentioned above. The hinge device 3000 includes a hinge mechanism 3100 and a damping mechanism 3200. The damping mechanism 3200 is used to generate resistance to the movement of the hinge mechanism 3100. The hinge mechanism 3100 and the damping mechanism 3200 are independent components.

[0082] In this embodiment, the hinge mechanism 3100 and the damping mechanism 3200 are independent components. "Independent" means that the function of the hinge mechanism 3100 is not affected by the damping mechanism 3200, and vice versa. The hinge mechanism 3100 only engages with the damping mechanism 3200 when the hinge device 3000 is assembled. For example, the hinge mechanism 3100 and the damping mechanism 3200 can be manufactured independently. The hinge mechanism 3100 has its own hinge function, and the damping mechanism 3200 has its own damping effect. Therefore, if the damping mechanism 3200 of the hinge device 3000 is damaged, it can be repaired and replaced separately. Similarly, if the hinge mechanism 3100 of the hinge device 3000 is damaged, it can be repaired and replaced separately. This eliminates the need to replace the entire hinge device 3000, effectively reducing maintenance costs.

[0083] It is understandable that, for different household appliances, the hinge device 3000 can have a damping effect or not. A damping effect means the hinge device 3000 has a damping mechanism 3200, while a non-damping effect means the hinge device 3000 does not have a damping mechanism 3200. In this embodiment, since the hinge mechanism 3100 and the damping mechanism 3200 are independent components, the presence or absence of the damping mechanism 3200 does not affect the movement of the hinge mechanism 3100. That is, when the hinge device 3000 needs a damping effect, the damper 3220 is installed; when the hinge device 3000 does not need a damping effect, the damper 3220 is removed. Through this design, the same set of hinge devices 3000 can freely switch between having a damping effect and not having a damping effect according to actual needs, without the need for separate molds for hinge devices 3000 with and without damping effects. This effectively reduces the amount of material, improves standardization, and thus increases production efficiency.

[0084] The hinge device 3000 of the household appliance in this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought about by the technical solution of the above embodiment, which will not be repeated here.

Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
